ter accurately with the impression onthe printing surface7 it isnecessary that thecard or sheet should be fed into the carriage andunder the platen rollerrand pressed on the printing surface ineXactlythe same position as the original.

` In my invention I. have provided a convenient means for accomplishingthe desired result and it has forone of its objects the provision ofacard or paper aligning and :feeding device which will allow the card orpaper to be automatically fed under the platen rollerand transferred tothe printing surface in a position to accurately register with theimpression.

Another object is to provide a device which will feed y and accuratelyregister cards of various sizes.

A further object is the provision of a feeding device arranged forfeeding a plurality of cards of the same or different size and providedwith suitable adjustable guides for accurately registering the cards.

Another objectis to provide an automatic feeding device which will beoperated by the movement of the carriage and which will not interferewith any ofthe normal Inovements or operations of the'carriage and itsassociated parts.

Further objects will appear from the de` tailed descriptionto follow andfrom the appended claims.

Referring now to the my invention7 asj illustrated7 comprises ahectograph frame l` supporting the Vusual gelatinized printing surface2, as illustrated in Fig. l, in which I have shown the carriage 3 in itsextreme forward position. This carriage is of the usual-,type andcomprises a substantially rectangular frame member l slidably mounted onthe rod 5 by means of `a suitable bearing 6 and arranged forlongitudinal movement over the'printing surface 2.' A platen rollerf ismounted in suitable bearings on the yoke 8' which is, in turn,v

pivotally supported inthe' carriage by means of the bearing rofl 9 andAis provided with a handle 10 for raising and lowering the platenroller, the platen roller cooperating with the pressure'roller 1l infeeding and removing the paper or card in the usual well-known manner.

In Fig. 1,I have illustrated the extreme forward position of thercarriage in full ew of one of the drawings in detail,

e f 6o ew of one ofthe lines, and in this `positionithe platen rollercured to the frame 4 by means of the screws 14 and at such an angle thatpaper or cards placed thereon will slide between the platen roller 7 andthe pressure roller 11 and be engaged and definitely located by themargin bar 12. A rod 15 is mounted inthe bearings 16 on the back of theprinting table and is provided with the L-shaped arms 17 0n which ismounted the stop member 18 which extends parallel with and adjacent thelower edge of the paper table 13. This stop member is normally held inthe position shown in Fig. 2 and in the dotted lines of Fig. 1 by meansol the spring 15a. and in this position cards or paper laid on the table13 will be held thereon.. The inturiied flange 18a engages the underside of .the guide plate 123 to limit the movement of the stop member18.

The depending arm 19 is secured to the shaft 15 and arranged to engagethe stop 20 on the frame 1 when the carriage moves to the extremeforward position. As the stop bar 18 is moved away from the edge of thepaper table the card or paper is allowed to slide between the rollersand en-y gaoe the margin bar.

uide members 21 are slidably mounted on the table'li and are eachprovided with a guide iange '22, the downwardly extending portion Q3having the inturned ilaiige 24 thereon.. These guide members arearranged to be clamped on the table, in a position to act as guides forany desired size of cards, by means of the thumb screws 25 andl theclamping block 26. The block Q6 rests against the inturned flange 24 andis clamped acainst the down turned {iange .27 on the table 13, asillustrated in Fig. il; by this means cards of any desired .ize may beused or by the use of a plurality of these ides cards of dii'l'erentsizes may be fed into printing position simultaneously.

In operation the platen roller is moved downwardly by means of thehandle 10 to engage the printing surface and the oarriage moved towardsthe rear of the machine, as shown by dotted lines in Fig. 1, where itengages a suitable, adjustable stop member 28 which is adjusted. tolimit the movement of the carriage to a position corresponding tothelength of the cards used. With the carriage in this position, the cardis placed upon the table 13, where it rests against the stop bar 18, andis held in lateral alignment by means of the guide member flanges 22.The carriage is then moved forward to the position shown in full lineswhere the card is released through the engagement of the lever 19 withthe stop 20.

It will be noted that when the carriage is in the forward position shownin Fig. 1, the cards or paper may be fed directly into the machine byhand in the usual manner, the

remise automatic feeding mechanism not interfering in any way with thenormal operation of the machine.

A considerable saving oi time is gained by placing the card on the guideplate when the carriage at the rear position., as the hand is then freeto rem..-ve the printed card as it is raised vfrom the printing surfacethrough the loiward movementvoi the carriage, in the usual manner.
